To all whom 'it may romern: l n

4lie it known that l. Usui: (i. llixnLi-rox. aeiizen of the lnited States. rer itlinj r at Girard, in the county ol Macoupin and Stateof illinois. hanl invented ne and urset ful lmprovenwnt` in lawomotivw. ot' which vIt() and in whit-h the air or motive tluid isnpplied hy compressors actuated h v internal combustion motors to tanlix in which it is stored under pressure and from which it is lsupplied .b v means .under control of the driver or engineerto the pneumatic. motors;

. A further ohjeet of the invention is to provide simple and etl'eetive meat.; for feeding air to the compressor and from the tanks to thc motor. for preventing: the .accumulation of pressure beyond a desired limit. and for 'ontrollinpr the feed to the motors to driveV the locomotive in either direi-tion.

A still further ohjeet ot' the invention is to provide an air hrake meehanimi supplied with an' from the Storage reservoirs. to provide a strong :ttul durahle frame structure` and to provide means for mounting the \\li"elttl tlua'li nl. the lm-olnolix'e to adapt them to accommodate themselves to both verticalv and lateral irregularities in the traelt' and relieve the frame and parts of the driving mechanism from the straitA to which they are ordinarily I ubjeeted.

'l'he frame of the engine embodies asuitable eentral frame structurel, a partially circular roof or canopy .l,.con'eavo convex end heads 3, and longitudinal side and.y trauweree end hars 4 and 5,- respectively, which support the roof or canopy and heads and are suitably connected with and supported from the central frame structure. The eanopy orerhangs and protects the Arnnninzgr gear and yworking,y parte` of the'engino and carries the engine cab 6, which mai` he arranged at. any suitable point along the length thereof.

` 'l`he frame or hotly of the locomotive as thus eonstruettal is carried upon any Suitahle num'ner of wheeled trucks i'. the wheels of whieh are positireltr driven from the engine gearing. ln the present in tanee a truel; is shown arranged at each end of the frame, eat-h truek comprising a pair of spared sections 8 formed of angle iron or other lauitahle material and each provided with hearings 9 for a pair of axles 10 carrying the traction wheels 11. The upper member of each bearing'f) is referably mov ably mounted and hackedy a spring 12 to permit the axles to have a sutiicient amount of yielding vertical play to take Each truck is swiveled upon the frame to rhave both vertical and lateral motion, be-

ing r provided with bear: .hrs 13 to receive trunmous 14 on a transverse yoke 15 having. a vertical passage 16 therein, on which 'tx-minions, the truck is adapted to oscllate in a vertical plane tc compensate for variations or irregularities l,in 'the height of the rails. The yoke is in turn provided with bearings 17 arranged at. right angles to the bearings 13 to receive trtmnions 18 upon a second yoke 19, which latter is adapted to have lateral oscillatory motion. The yoke 19 receives a hollow stem 2O projecting downward from a. cross bar 21 fixed .to the longitudinal frame hars 4', said stem being secured to the yoke by one or more bolts or other suitable fastenings 22,. whereby the truck is detachably secured to the frame and a. relative lateral mot-ion Vbetween the truck and ylocomotive bodv permitted to adapt the wheels to easily follow curvatures und lateral irregularities in the track. It will thus be seen that a novel and cculiar construction of swivel or univeisa joint connection between each truck and the body or frame is provided 'to permit the truck to adapt. itself freely to both vertical and lateral irregularities in the' track without throwing strain upon the frame structure.

The frame structure is reinforced by one or more longitudinal tie bars 23, each having a horizontal portion fixed to the central frame member 1 andoutwardly and downwardly inclined end 'portions fixed tothe heads 3, whereby the latter are strengthened and braced and rigidly coupled to the said central frame member. Supported by the central frame member and hung by bands or straps :'Zlfroni the frame bars 4; is a main or primary air storage tank 25, which tank 1s provided at -its ends with openguide brackets 26, each having a pair of spaced grooved guide pulleys 27 mounted therein on vertical axes. "The sections of each` truck 7 are connected at their rear ends by arcuate mide rods 28 which extend through the' )rockets and run in contact with the pulleys, which brackets and rods form connections to limit the lateral movements of the truck and prevent. strain from coming upon the yokcs from the jars and concussions received in coupling the locomotive to cars.

Arranged above and on each side of thc main storage tank 25 :ire supplemental or auxiliary storage tanks 29, one of which is herein shown, each of which tanks 29 is coupled to the tank 25 by a gasket or air tight coupling connection 30, in which is formed a port or passage 31 for the How of air between said reservoir. This `port is controllcdby a check valve 32 having a stem 33 movable in a guide bracket 34 and normally held closed by a spring 35. Compressed air is supplied to and stored in the tank 25 in the manner hereinafter described and flows therefrom through the ports 31 into the tanks 29. The tank 25 is in communication with an air chest or storage box 36 arranged in the engineers cab 6 throu h feed pipes 37. 'Ifhis chest extends over t e tanks 29 and is in direct communication therewith through ports 40, whereby thc air contained in the tanks is supplied to the chest for service in driving motors hereinafter described. The pipes 37 and ports 40 are provided with valve seats adapted to be engaged by valves il each mounted upon a stem .having .a screw threaded enga rement with the chest, as at 42, and provi ed with an angular' upper end 43 for the ap- I .plication of a crank or handle 44, by which communication between the-tanks and the chest may be cut otl` or controlled asl desired.` Preferably,adriving motor is mount` ved upon each individual truck and the chest chambers. By this means the supply of,4

conpressed air tok the niotors may indepen .ently controlled. Arrangedwithin the cab is a rack 46 supporting a series'of ages .47, communicating with the parts o? lchest and feed pipes `of the apparatus by which the pressure in the tanks and diti'erent. feed connections may be readily determined at any time. f

Compressed air is supplied to the tank .25 by a pair of air compressors 48 sup in longitudinal aliiieinent below sai tank upon the frame portion 1. .Each of said compressors comprises a cylinder 49 having a piston 50 operating therein, said pistons.

being coupled by connecting rods 51 to a crank 52 onthe shaft of a gear wheel 53 mounted between the com rcssors'. Each cylinder 49 is provided wit an inlet port '54 controlled by a check valve 55 und with a discharge port 56 controlled by a check valve 57. The inlet ports 54 of the compress` ors arc connected by pipes 58 with a main vir supply pipe .S9-extending longitudinally the orted i A of the engine, and the ends of which communicatc with air feed ports 60 in the concnvo convex or conical heads 3, which ports are respectively controlled by inwardly movable check valves 61. When the locomotive is in motion, nir will be gathered by the for- Vward conical head and flow back through the pipe 59 to thek compressors, the forward valve 51 opening for the admission of the air, while the rear valve 61 closes underthe resultant pressure to retain the collected air within the pipe.

The air compressors are driven by inten nal combustion or gasolenc engines 62 of the duplex lcylinder type, each having itscylindeis arranged in tandem and its istons coupled for movement in unison. he pistons of the two internal combustion engines are connected b rods 63 with a crank 64 o n the shaft of u rive gear or pinion 65 which meshes with and imparts motion to .y

the gear 53, whereby the compressors are driven. Gnsolene Storace tanks 66 are suit, ably mounted beneath the cano y 2 and are connected with the engines by eed pipes 6 7, in each of which any suitabletype of' carburetei may be arranged, as shown in Fig. 10.
